Fig. 11 is an enlarged detail of rods 31 and cooperating parts.

Referring to the accompanying drawi s, illustrating by way of exampleone emb ment of the invention, means are provided, in accordance withone feature of the invention, for maintaining a supply of rivet formingrods, and for heating same and for cutting off" therefrom rivet blankspreparatory to forwarding same through the machine to rivet the worktogether. means, in accordance with one feature of the invention,simultaneously handles or provides for the full complement of rivets fora given joint in the work, the blanks therefor bein all simultaneouslyforwarded to the mac ine and all the rivets formed simultaneously in theWork.

Said

As embodied, the rivet making material is preferably in the form ofround rods 0. suflicicnt in number for the particular kind of work beingdone. The embodied form of heating means for the rods comprises a gasmuflle 1 of suitable refractory material, having a plurality of tubes 2,vertically arranged, within which are the vertically positioned rods a.The mutlle will be of suitable construction, and so far as concerns thebroader features of the invention, other forms of heating devices can beused.

Means are provided for cutting oil from the heated rod or rods pieces ofright length for forming the rivets, and further for simultaneouslycutting off from a plurality of the heated rods the proper number ofblanks for the number of rivets required to complete a particular jointin the work being operated upon by the machine. As embodied, the rods aproject through the bottom end of the heating device, such as themuffle 1. (See Figs. 1, 6 and 7.) Beneath the mufile 1 is shown a plate4 having apertures 5 therein corresponding in number to the rods used,wh ch apertures contract or are beveled toward their bottom or outeredge. Traveling reciprocably beneath the plate 4, 1s a plate 6, having aseries of apertures 7 therein corresponding to the apertures 5 in theplate 4. Fixed to theplate 6 to travel reciprocably therewith is a plate8, said plate 8 havin therein a series of apertures 9 corresponding tothe apertures 7 in the plate 6. The plates 6 and 8 are connectedtogether by a suitable connecting piece 10, plate 8 being verticallyadjustable, the .structure being mounted on suitable guides on the frameof the machine. The

connecting piece 10 is provided with arms 11, which embrace a rod 15,having its bent or'ofl'set ends 18 engaging in the angled slots 17formed in the eccentric rod 13 (Figs. 1, 2, 4, 5 and 17). Rod 13 isreciprocated by an eccentric I? on shaft 108 (Figs. 1, 4, 5 and 17). Theends 18 of rod 15 are supported by rock arms 16, mounted on a shaft 12,which shaft is mounted in brackets on the frame of the machine (Figs. 1,2, 4, 5 and 11). The tail 19 of rod 13 is bent to rest upon the topreach of frame 80 (Fig. 1). Thus when frame 80 moves to the left in Fig.1, rod 13 drops and does not actuate plate, but when frame 80 is at ornear its'extreme right hand position, it engages tail 19 of rod 13 andplate 10 is actuated at the proper time to cut oil the rivet blanksfromthe rods a.

Beneath the plate 8, and preferably in sliding contact therewith, is aplate or other supporting structure 20, carrying a plural ity of tubes21, w ich tubes are adapted to receive the rivet blanks cut off from therods a and to transmit the blanks to suitable fOl warding devices. Thehot out 01f blanks 7) from the tubes 21 are dropped into receivingapertures 22 in a slidable-block 23, which block serves as a conveyor ofthe blanks 0 toward the work. For the purpose of discharging or passingon the blanks b from the carrier 225 at the proper time, the bottom 24of the block is slidably mounted upon the block 23 and is spring pressedtoward the left (in Figs. 1, 6, 7 and 8) by springs acting on bent-uplugs 26 formed upon the bottom plate 24. In the bottom plate 24 are a.series of apertures 27, which apertures are out of alinement or registrywith the tubular apertures 22 in block 23 when the bottom plate 24 ismoved to the left by the springs 25.

8O Pivotally mounted upon the block 23 are tripping fingers 28, beingpivoted to brackets 29 fixed on the block. The fingers 28 extend throughapertures in the bottom plate 24, and the arrangement is such that asthe block 23 travels to the left, the fingers 28 at the proper timeencounter a suitable stop, and the bottom plate 24 is moved to theright, thus bringing the apertures 27 into alinement with the tubularapertures 22, and the rivet blanks are thus permitted to dropdownwardly, or to be pushed, through the apertures 27 in the bottomplate 24.

The manner of operation of the previously described mechanism issubstantially as follows:

The heated rods a, vertically arranged in the muflles 1, rest upon thetop surface of the plate 6, as the plate (3 travels toward the right inFig. 7. As the apertures 7 and 9 come into alineinent or registry withthe apertures 5 (as shown in Fig; 6), the rods a drop downwardly andrest upon the top surface of the plate 20. The apertures 5 and 7 are soformed that their contacting edges form cutting surfaces. As the plates6 and 8 start toward the left in Fig. 6, the rods a are cut of? at thecontacting faces of the plates 4 and (S, leaving the cut off bottom endsof the rods a as a gang or complement of blanks b of the right lengthfor the rivets to be formed and supported in the plates (3 and 8. As theplates 6 and 8 travel to the lcft to the position shown in Fig. 7, thisseries or complement of blanks is car-- ried forward in verticalposition. The lower ends of the rods a are supported upon the uppersurface of the plate 3 until the completion of the return travel of theplates (3 and 8 as already described. As the plates 6 and 8 travel tothe left from the position of Fig. (3 to that of Fig. 7, the apertures 7and 9 come into registry with the tubes 21 carried by the plate 20, theapertures 22 in block 23 being in line beneath tubes 21. There-upon thegang or series of hot rivet blanks 71 drop downwardly, directed by thetubes 21,. into the tubular apertures 22 in the block 23. The block 23then moves to 13 meme I "V L h A alhe left from the position shown inFig. 7 to t at shown in Flg. 8, wherein the rivet reo ceivingtubes 47and the tubes 22 are in in connection with the description ofnthestructure itself. i i

In the embo ied form of such'means, thereare provided three-sided rectangular frames and 81 reciprocably mountedrespectively at each side of the machine in guideways formed in the sideframe of the machine. The frame 80 is mounted in guide-ways 82 and 83 inone side frame, and the frame 81 is mounted in guide-ways 84 Formed onthe lower edge of the lower reach of the frame 80 is a straight gear 86,and a corresponding straight gear 87 is formed on the lowermost reach ofthe frame 81. Meshing with the gear 86 is a pinion 88, and meshin withthe gear 87 is a pinion 89, both said pinions bemg mounted upon andfixed to rotate with a driven shaft 90.

In the preceding description and statement of operation, the rogre'ssthrough the machine of the rivet b ank b was described up to the pointof their deposition in the block 23.

The block 23 is carried upon and between the upper horizontal reaches ofthe frames 80 and 81, and thus travels to and fro with said frames fromthe position beneath the tubes 21 (Figs. 6 and 7) where it receives therivet blanks to a position above the a ertures 47' (Fi 8) into which itdisc arges the rivet b anks preparatory to their being forced into therivet holes in the work, the block 23 then passing onward to the left(Figs. 4 and 5) to permit of the riveting tools operating on the rivetsthrough apertures 47.

In the embodied form of riveting means, plungers engage the rivet blanksby in the apertures 47 in the clamping block 48 and force them throughthe rivet holes in the work and into cont t with rivet head formingplungers which ome through the apertures 47 in the clamping block 41into: osition at the opposite end of the rivet oles in the superposedshapes (Figs. 4 and 5). Further, as embodied, said riveting toolscomprise a series of plungers 98 mounted in a supporting plate 99, saidplungers having heads 100 resting in enlarged recesses in the u persurface of the plate 99, the shanks o the lungers 98 pro ectindownwardly throng apertures in the p ate 99. The ends of the plate 99rest respectively in the guide-ways 82 and 84. One end of the plate 99has its vertical edges beveled and fitting between projections 94 and 95(Fig. 10) upon the upper horizontal reach of the frame 80. The other endof the plate 99 also has its vertical edges beveled and resting betweenpro'ections 96 and 97 Fig. 10) on the upper orizontal reach 0 the otherreciprocating frame 81. Vertically disposed guide-ways are formed in oron the vertical portions of the side frames, at guide-way 101intersecting the guide-way 82, and on the other side. of the machine acorresponding vertical guideway intersecting the guide-way 84.Reciprocably mounted in said guide-way 101 is a head 103. Said head 103is pivotally carried by connecting links 104.- at either side thereof,said links having respectively eccentrics 106 and 107 upon driven shaft108. The lower part of the head 103 (Fig. 2) has an undercut ordove-tailed extension 109,'and on the upper f cc of the plate 99 areformed corresponding projections 110 and 111, whereby the plate 99 as itreciprocates may pass into and out of engagement or operative connectionwith the head 103.

0n the lower horizontal reaches of the two frames 80 and 81 are mountedsupports for the coiiperatin formers for the opposite heads of therivets, which formers enter through the apertures 47, comin up to theends of the rivet holes on the un 1' side of the shapes to form therivet heads on the blanks as they are forced through by the pluugers 98(Fig. 5). Mounted in a. supporting plate 121-is a series of suchplungers 120. The supporting plate 121 may be similarly constructed andarranged relatively to the guideways 83 and and relatively to the lowerhorizontal reaches of the frames 80 and 81 as the arrangement andconstruction of the plate 99 relativel to the guide-ways 82 and 84(described a ove and shown in Fig. 10) and detailed description thereofwill be unnecessary. Reciprocablv mounted in the. lower part of theguide-way 101 is a head 74, previously referred to. Upon the uppersurface of the head 74 is an undercut or dove-tailed projection 122, andthe supporting late 121 has projections 123 and 124 form thereon vwherebin its reciprocatory trayel said plate 121 wil pass into and out ofengagement with the head 74.

In the apertures 47' there are provided means for lightly holding therivet blanks until the forming plungers beneath are in of the invention,and the embodied means for this purpose comprises a series of an portingrollers 127, which may be idle ml ers or driven rollers as desired orfound convenient,

frames 80 and 81 (Fig.

The'm'annerof operation of the mechapisms just described issubstantially as folowsz' It may be assumed that the work is an I-beamand its two angle plates, and that the parts have been positioned asshown in Fig. 1. The lowermost angle is laid in position upon itssupporting block and aliner 40, the beam in is run in, and the upperangle is placed in position with respect to its aliner 40, and theshaft64 is rotated in the proper direction to bring the blocks 41 and 48together to grip the work, the alining fin era 42 I'GSSll'lgllhB twoangle plates 3 an 2 against their respective aliners 49. The supportingplate 72 for the alining fingers is in position with respect to thevertical guideways 101 in the frame, and the plate 72 1s also inengagement with thewpart 122 of the head 74. As the shaft 77 rotates the.head 74 is pushed upwardly,-and the 'frames 80 and 81 are s id towardthe left in the guideways 82 and 83, and the guideways 84 and 85,respectively. It will be recalled that the rivet blanks b are resting inthe apertures in the block 23 upon the bottom plate 24. As. the block 23slides to the left, it passes from the position shown in Fi 7 to thatshown in Fig. 8. As it approac es the position shown in Fi 8, the triping fi ngers'28 encounter the ge of the ang e y, or some other suitable1:: 1p, and the bottom plate 24 isslid against its spring 25 and theapertures 27 in the bottom plate 24 are brought into alinement with theblanks b.

The block 23 pauses momentarily and the blanks b are dropped into theapertures 47, and are sli htly held by the spring fingers 126. (See ig.4). frames 80 and 81 to the left continuing, the upper plate 99 carryingthe plungers 98, and the lower plate 121 carrying the plungers 120, comeinto alinement with the vertical guide-ways 101. It will be understoodthat these plates are carried along horizontally by means of their enagement with the 10%, and the late 99 rides onto the promotion 109 upont e head 103,'and the plate 121 rides onto the projection 122 upon thehead 74. By the rotation of the shafts 108 and 77, the series or gang ofplungers are brought up into [JOSI- tion against the lowermost angleplate 2 as shown in Fig. 5, and the gen of plungers 98 entering theapertures 4 force the blanks 6 through the rivet holes in the work hehead 74,

The movement of the and into the recessed heads of the opposed plungers120, and the rivets are thus completely formed in position in the work.As the heads 74 and 103 recede, they carry backward the supportingplates 99 and 121 until plate 99 passes into alinement with theprojections 94 and 95 on the frame 80 and with the projections 96 and 97on the frame 81, and plate 121 passes into alinement with thecorresponding projections on the bottom reaches or sides of the frames80 and 81. The frames 80 and 81 begin their return reciprocation, to theright in Fi 1, and the plates 99 and 121 pass to the rig it therewithand out of engagement, respectively, with 80 the heads 103 and 74. Themovement of the frames 80 and 81 to the right continues until themechanism is brought again to the position shown in Fig. 1.

By the process included in myinventio n; a hot blank, or series ofblanks, is cut of precise length and sizefor the particular; rivet orseries of rivets to be formed, and such blank or series of blanks, isforced into the rivet holes in the assembled work;an d the entire rivetis formed in the work, fF1irthermore by my process, the ends' of theblank are sllghtly chilled in the cuttin' and when the rivet is formedin the wor: the; central portion thereof, that is the portion formingthe stem of the rivet is slightly more plasticor fluent than the two'ends'of the blank, and the resulting pressure insures 5 that the entirespace ofjthe rivet holes' through the work will be completelya'nd'fwfltightly filled making a fixed and rigid and unusually strong joint. Bymy recess also the rods are continuously fed through-the furnace andkept at the required tempera-j? ture, and the blanks are cut elftherefrom 'af-lop complete series or gang at a time as neededz By myrooess the blanks are cut off whilehot, and are headed and completelyformed in the work while so heated, the headsKon' each end of the blankbeing simultaneously"11g formed. h In accordance with one feature of the"invention the riveting dies and plungeis, the heating furnaces or otherheating means," and various other parts are removable and11 5interchangeable with respect to the other parts of the machine, 'wherebyrivets andwork of different sizes may be operated upon, and gangs orseries comprising 'dif-* ferent numbers of rivets may be used at onetime. i

Suitable driving devices are provided, and as embodied a suitable motorhas a pinion meshing with a gear 137. Fixed to'the shaft of gear 137 isa pinion 138 meshing'n with a gear 139. Fixed to gear 139 is clutchmember 140. Gear 139 and its clutch mem her are loosely mounted on shaft141. Splined to shaft 141 is a pinion 142,1and fixed to pinion 142 isthe companion clutch member 143 for the member 140. Fixed to pinion 142is a flange 144. A spring 145 IS coiled about shaft 141 and is incompression between flange 144 and a collar 146. Meshing with pinion 142is a gear 147 carried on a stub shaft journaled in a heaping 148. Thepinion 142 and gear 147 are in" a three to one ratio.

Carried on gear 147 is a sliding cam 149, which is spring impelledoutwardly, by spring 150. Cam 149 is adapted to engage flange 144 andseparate clutch members 140, 143 to stop shaft 141. Cam 149 is left inposition for so holding out the clutch, and thus keeping shaft 141 atrest, until said cam 149 is withdrawn against its sprin 150, when theclutch members are "moved into engagement by spring 145 and shaft 141 isagain rotated. The illustrated means for moving cam 149 back against itsspring comprises a lever 151 pivoted at 152. TlllS lever is actuatedthrough suitable connections 153 from a foot lever 154. Mounted on shaft141 is a gear 155 driven by shaft 141 but havin an intermittent motlondevice interpos and which will be hereafter'described. A gear 156 mesheswith gear 155, the gear 156 being fast on shaft 108. A correspondinggear 157 is fast on shaft- 77. The requisite periodic or intermittentreciprocatory movement is given to plunger heads 103 and 74 by theirrespective shafts 108 and 77 with the intervening eccentric and linkmechanism (Figs. 1, 4, 5, 12 and 13 The'em odied form of actuating meansfor the reciprocating frames 80 and 81 comprises a periodic,intermittent drive for shaft 90. Fixed on shaft 141 is a pinion 158, andmeshing therewith is a ear wheel 159 loose on shaft 90. Also fixe onshaft 141' is a pinion 160. Pinion 160 meshes with an idle pinion 161,mounted on a stub shaft on the machine frame. Meshing with idler 161 isa gear wheel,162, likewise loose on shaft 90. Fixed to get! 162 is aclutch member 163, and a simi ar clutch member 164 is fixed to the otherloose gear 159. Between clutch members 163 and 164 is a sliding clutchmember 165, splined on shaft 90 and adapted to pass into and out of engement alternately with the clutch mem ers 163 and 164. As gears 159 and162 travel in opposite directions, clutch member 165 serves to reversethe direction of rotation of shaft 90 and correspondingly the travel offrames 80 and 81. For the purpose of sliding clutch member 165, there isprovided an annular groove 166 therein. Working in said groove 18 ayoked bell crank lever 167 pivoted at 168. The other end of said lever167 bears on a cam 170, carried on gear 162. Spring 171 holds the bellcrank lever to cam 170.

e intermittent motion, previously referred to, is imparted to gear 155for the purpose of correlating the movements of plungers 103 and 74 withthe movements of frames 80 and 81, and the coi'ipeiatino devices, as forinstance the passing of the plunger carriers 99 and 121 from the frames80 and 81 onto the heads 103 and 74 and their detachment therefrom. Asembodied, a gear wheel 155 is sleeved on shaft 141 by a sleeve 174,which sleeve has splined thereon a clutch member 175. Said clutch member175 coiipcratcs with a clutch member 176 fast to pinion 158. Clutchmember 175 is urged into engagement with member 176 by a spring 177. Ayoked bell crank lever 179 engages in an annular groove 180 formed onclutch member 175. Lever 179 is pivotally mounted at 181, and has anoffset arm 182 bearing on cam 183 fixed to gear 159. Gear wheel 159 andits cam 183 rotates and stops with shaft 141, as already described, andgear 155 is correspondingly started and stopped. In addition, by themechanism just described, the requisite intermittent movement and dwellis imparted to gear 155 during the rotation of shaft 141.

Means are provided for imparting proper movement to shaft 64, and theexemplified form thereof comprises a friction drive 184 connecting witha shaft 185. Loose on shaft 185 is a sprocket driven clutch member'186,driven by a sprocket chain 187, from a sprocket wheel 188, whichsprocket wheel is fixed to pinion 158. Also mounted loosely on shaft 185is a sprocket driven clutch member 189, driven by a sprocket chain 190from a sprocket wheel 191, fixed to the idle or intermediate pinion 161.Thus clutch members 186 and 189 are driven in opposite directions.Splined on shaft 185 between said clutch members 186 and 189, is a twofaced clutch member 192. A yoked bell crank lever 193 engages in anannular groove 194 in clutch member 192. The other arm 195 of the bellcrank lever connects to a pivoted, spring pressed rod 196. Said rod 196is reciprocated by a cam 19? fixed to gear 162, (which also carries cam170%. Thus the proper intermittent reversib e rotary movement isimparted to shaft 64, and by the friction drive a firm clamping actionis exerted upon the assembled shapes. Means are provided by theinvention for determining and regulating the length of rivet blanks tobe cut oil from the rods a so that the blanks will be of just the rightlength for-the rivets in the particular work being operated upon. Asembodied, said means comprises a vertical adjustment for the block 20upon the upper face of which block the lower ends of rods a rest priorto cutting. The vertical positioning of block 20 is effected ordetermined by slidable wedges or cams 200,working in guideways in themachine frame and working under correspondingly beveled hearings orextenteem sions 201' on the block 20 (see Figs. 12,13 similar and neednot be further described .a. and 14) Therwedges or cams 200 are conindetail. 4 i nectedzg p votal' mks 202 to, hell crank The embodied forniof means for varying levers ,p1'voted at 204.- The other arms thepositionor travel of the rivet forming 5 205 02 said bell cranks are inthe jgaths of devices comprises devices intenposable in 70 extensions206 on clamping block 4 Thus varying magnitudes between the carriers forthe position of clamping block-48 bein dethe rivet formingidevices andthe plunger ternuned by the thickness of the assem led heads 103 and 74which carry'them to and work, the cams 200' are likewise positionedfrom' the work.
